Pulmonary Vein Reconnection in Patients With and Without Atrial Fibrillation Recurrence After Ablation.

Since the landmark observation by Haissaguerre et al. [(1)][1] of rapid pulmonary vein (PV) firing at the onset of paroxysmal atrial fibrillation (AF) ablation targeting PVs and/or PV surrounding atrial tissue has remained the cornerstone approach to catheter-based treatment of AF [(2)][2]. Two
